POM for unknown.binary：mysql-connector-java-5.1.23-bin：jar：SNAPSHOT丟失，沒有依賴信息可用

Question

我在構建我的項目時遇到了標題中顯示的錯誤，我相信試圖在tomcat中運行時出錯的原因。下面添加了POM。

希望有一些簡單的我」

你可以修改和包含版本信息的依賴信息mysql-connector。像下面，然後再試一次， 我希望maven是無法下載mysql連接器jar，你可以通過檢查，將jar放到IDE的外部庫部分來驗證這一點，在這裏所有jar下載的maven都會顯示出來： -

<!--Mysql-Connector--> 
     <dependency> 
      <groupId>mysql</groupId> 
      <artifactId>mysql-connector-java</artifactId> 
      <version>5.1.36</version> 
     </dependency>
